Peanut Extrusion is an easy to use structure. The profile of the extrusion looks like a peanut and has two holes that are perfect for a 1/4-20 thread-forming screw. The added mid spans are positioned to flank a pair of bolts that self thread into the adjoining peanut extrusion. These spans prevent the peanut from getting crushed by over tightening the bolts. The advantages of Peanut Extrusion are the ease of creating rigid corner joints and the closed profile of the extrusion that prevents dust build up. Whether you are making a table in your shop or a strong frame for a robot, this extrusion is the one for you! Specifications:
